33 points if someone gets it right.

On Finn's shelf are the following books. 12 drama books, 3 history books, 4 romance books, and 11 adventure books.

If Finn randomly picks one book to read, what is the probability that he selects a romance book.

Answer 1

P(Romance) = 4/30 = 2/15

Explanation:

There are 12+3+4+11=30 total books, and 4 of them are romance. Therefore, the probability that Finn will select a romance book is 4/30, or 2/15 simplified.

Answer 2

Probability = 2 / 15

Explanation:

To calculate the probability of Finn selecting a romance book, we need to determine the ratio of the number of romance books to the total number of books on Finn's shelf.

Given the following information:

- Number of drama books: 12

- Number of history books: 3

- Number of romance books: 4

- Number of adventure books: 11

The total number of books on Finn's shelf is the sum of all these categories:

Total number of books = Number of drama books + Number of history books + Number of romance books + Number of adventure books

Total number of books = 12 + 3 + 4 + 11

Total number of books = 30

Therefore, there are 30 books in total on Finn's shelf.

The probability of Finn selecting a romance book can be calculated by dividing the number of romance books by the total number of books:

Probability = Number of romance books / Total number of books

Probability = 4 / 30

Simplifying the fraction, we have:

Probability = 2 / 15

Hence, the probability that Finn selects a romance book is 2/15 or approximately 0.1333 (rounded to four decimal places).
